The reaction of propargylic alcohols with diaryl disulfides and carbon monoxide in the presence of tetrakis(triphenylphosphine)palladium leads to a novel thiolative lactonization to afford beta-(arylthio)-alpha,beta-unsaturated lactones in moderate to good yields. Similar conditions can be employed with homopropargylic alcohols, giving the corresponding delta-lactones with a beta-arylthio group successfully

3- and 4-trialkylstannylfuranones (2) and (3) have been prepared by an interesting desulphurative stannylation reaction; 3- and 4-substituted 2-(5H)-Furanones (12) and (13) may be prepared via palladium-catalysed cross coupling of (2) and (3) with aryl iodides
